So i have a sbc 350, it is bored .60 over, has a mild cam, and 305 heads. The compression is about 11/1. It was just rebuild about 300 miles ago, and it has a single plane intake on it. Ive been told that this is the wrong intake for stock heads, and that i should put a dual plane on it. Is this true? If so what would be a good intake/carb setup for this motor?
